Zirconium products in energy storage applications

Can zirconium oxide be used as a supercapacitor electrode?

Among various oxides, zirconium oxide (ZrO 2) finds vast applications due to its features such as high melting point, non-toxic nature and corrosion-free property [ 10–13 ]. However, the instability as well a higher electrical resistance retards its use as a electrode for supercapacitor applications.

Does silver coating improve electrochemical performance of zirconia nanoparticles?

The phase, purity as well as the morphology of the materials were confirmed by XRD, UV/Visible, EDX, SEM and TEM techniques. Silver coating effectively improved the electrochemical performance of zirconia nanoparticles, which was due to the enhancement of electrical conductivity and specific surface area of zirconia nanoparticles.

Does silver-coated zirconia have a peak of AG?

(a)) while in silver-coated zirconia, an additional peak of Ag was also observed. The absence of the peak for any other element in the synthesized materials confirmed the purity of these materials. The surface area, pore volume and pore size were determined by the nitrogen adsorption–desorption isotherm.

What is the specific capacitance of silver-coated zirconia?

The silver-coated zirconia showed higher specific capacitance of 792 F/g at 10 mV/s as compared to individual zirconia (10.22 F/g). Silver-coated ZrO 2 also showed good power density of 274.5 W/kg at current density of 5 mA/cm 2 through the galvanostatic charge discharge profile.

Is silver-coated ZrO 2 more conductive than simple zirconia?

So, it can be inferred that silver-coated ZrO 2 is more conductive in nature as compared to simple zirconia and stimulates the electrochemical performance [ 32, 33 ]. 4. Conclusion Silver-coated ZrO 2 nanoparticles as an electrode structure were synthesized successfully using two step methods, i.e. simple co-precipitation and the reduction method.

Can silver-coated ZrO 2 be used as a supercapacitor electrode material?

Hence, the results suggest that silver-coated ZrO 2 showed improved electrochemical performance as compared individual ZrO 2 due to higher electrical conductivity and specific surface area. Hence, silvercoated ZrO 2 nanoparticles can be employed as an electrode material for supercapacitor applications. 1. Introduction
